Thickness measurements of sheets and plates with horizontally polarized guided plate waves -SH-modes- and electromagnetic ultrasonic EMUS-transducers


A new developed self-calibrating ultrasonic technique for the thickness measurement of high alloyed steel sheets with a strong variation of the sound velocity is described. It is based on the features of guided SH-Modes, namely no dispersion of the lowest mode SS sub O and dispersion of all other modes and transduction of the ultrasonic waves by EMUS-transducers. (IZFP
